thanks for the support!
Earlier this spring I was shopping for a UL pack. After trying - and returning - a few sub 2 lb packs, I finally found the pinnacle and chose it. the Jam is smaller, but I liked the volume flexibility with the pinnacle. it actually fits and carries quire well.
At some point, I'd like to buy a pack that weighs less than 2 lbs, but for now, I'm very happy with my pinnacle.
